Title: Improvements in or relating to parachutes
Inventor: MITCHELL JOHN ROTHWELL
IPC: B64D17/34
Filed: 1968-07-10
Abstract: 1,240,323. Parachutes. G. Q. PARACHUTE CO. Ltd. 5 June, 1969 [10 July, 1968], No. 32793/68. Heading B7G. When a load 15, Fig. 2, is dropped, a stabilizing canopy 11 connected thereto by a webbing strop 14 deploys and the main canopy 17, tightly reefed around the strop 14, is dragged from the pack 13. Dereefing of the canopy 17 is effected by unlocking parts 24, 25, Fig. 5, of a strop coupling which are dragged apart by the pull of the canopy 11, the consequent movement of strop 14 relative to canopy 17 being sufficient to allow pins 28 to be pulled from dereefers 27, whereupon reefing cords 30 are released and canopy 17 deploys. If the crown of the main canopy has been held in a depressed position 22, Fig. 2, this is maintained until the main canopy has inflated sufficiently for ties 21, Fig. 3, connecting a crown vent ring 18 to strop 14, to be broken, when the main canopy 17 becomes free to inflate fully. Dereefing of the canopy 17 can be initiated manually or by mechanical means in specified locations operated by time-controlled or barometrically operated mechanisms or by mechanisms operated by radio or light signals. The vent ring 18 may be provided with a sleeve 19 for protection of the vent ring tapes, and equipment can be provided to dereef the main canopy in stages, to give more than two rates of descent.

Title: Water treatment system
IPC: G05D21/02
Filed: 1971-07-13
Abstract: 1361292 Electro-retroactive control of water treatment system J A SCHLEIMER 13 July 1971 32831/71 Heading G3R A water treatment system for control of scaling and corrosion caused by recirculating evaporative water used with heat exchange equipment comprises separate electrode means, immersed in the water to be treated, to sense electrical properties of the water significant of corrosion rate Fig. 4, (not shown), pH Fig. 5, (not shown), and concentration of dissolved solids by measuring conductivity Fig.3, (not shown), respectively. The electrode means are each connected to a respective comparator circuit which produces an output signal when the actual value sensed exceeds a predetermined desired value. The three output signals are fed to a monitor circuit Fig. 6 which accordingly operates equipment to restore the water to the desired condition. In addition the monitor circuit may operate alarms and indicator lamps when any one of the sensed parameters exceeds the desired level thereof. The monitor circuit Fig. 6, includes a motor driven reed switch 140 which generates timing pulses (e.g. one every 5 minutes) to initiate and time corrective actions. These pulses are applied to a pH pulse counter 154, a conductivity pulse counter 168 and a corrosion rate pulse counter 172. These counters are controlled by respective gates 148, 150, 152. When an error signal output from a comparator occurs it operates a respective switch which applies a voltage to the appropriate gate. In the case of the pH comparator for example, when the switch is operated it applies 115 volts A.C. to an input of pH gate 148 the resulting output of which causes a reset voltage (e.g. 5 volts D.C. from a source not shown), which holds the counter 154 at zero when no error signals are present, to disappear. The timing pulses are thus permitted to act on the counter. At the same time the 115 volts A.C. is applied to energize a pump 16 which adds acid to the water. When the counter 154 reaches a predetermined number of counts e.g. eight, a transistor 156 conducts and energizes a relay coil 158 which closes contacts 155 thus shunting the input of the counter to earth and stopping the count, and opens contacts 14 stopping the pump and closes contacts 14-1 so that a bleed valve on the water circuit is opened. The corrosion and conductivity gates and counters operate respective correction facilities and alarms in a similar manner. The output of the corrosion rate counter for instance functions to control a repretreat pump and the bleed valve and may also act via relays 176, (182) Fig. 1, (not shown) and contacts (18) to stop the acid pump. The conductivity comparator Fig.3, (not shown), is provided with a dead band feature and the output of the conductivity counter may operate an inhibitor pump, the bleed valve, a recorder and an alarm.

Title: Improvements relating to the filtration or the decolorisation of sugar and other liquors
IPC: C13B20/12
Filed: 1922-12-06
Abstract: 210,232. Russell, M. Dec. 6, 1922. Filters with loose filtering-materials.-Charcoal or other carbonaceous medium for filtering sugar or other liquors is revivified in the filter chambers by passing through the chambers superheated steam at a temperature of 600‹ F. or above. The medium may afterwards be cooled by introducing low pressure saturated steam, which is thus superheated and may be used in revivifying the medium of another filter. Air may be introduced with the superheated steam so as to decarbonize the medium. Or air may be used to cool the medium after the treatment with superheated steam. Before the revivifying treatment saturated or superheated steam, with or without water, may be passed through the medium to recover sugar in solution therefrom. The temperature of the combined steam and water used for this purpose is preferably between 200 and 220‹ F. The filters may be lined with fire-brick or other non-conducting material and may be lagged outside.

Abstract: 928,429. Discharging pleated cups from a stack. MOIRS Ltd. Sept. 19, 1961 [March 8, 1961], No. 33597/61. Class 78 (1). Pleated paper cups are dispensed on a surface one at a time from the bottom of a nested stack C. As shown in Fig. 3 a mandrel 24 engages the cohering stack C and retains it frictionally. The lowermost cup is brought into contact with a receiving surface (not shown) by lowering the device by hand or by a machine. Once contact with the surface is established continued pressure causes the mandrel 24 and all the cups except the lowermost to rotate by a pin (not shown) co-operating with a curved slot 26. The cohesion between the lowest cup and the next above is thus broken and the device may be withdrawn leaving the lowermost cup on the surface. The action may then be repeated. The embodiment shown in Fig. 6 has a thumb member 43 and finger grips 49. Rotation may be caused by wedges (Fig. 4, not shown).

Abstract: 901,571. Variable-speed gearing. WAYMOUTH, H. Jan. 4, 1961 [Oct. 5, 1959], No. 33617/59. Class 80 (2). A shift mechanism for a V-belt 3 connecting stepped pulleys 1, 2 consists of horizontal arms 14, 15 carrying pairs of jockey pulleys 16, 18 and 17, 19, respectively, and supported on a vertical member 9 mounted for vertical movement on parallel links 10 operated by a hand lever 24. The pulleys 16, 17 adjacent the larger drive pulleys are incapable of relative vertical movement, while pulleys 18, 19 adjacent the smaller drive pulleys are carried by arms capable of movement in the vertical plane about pivots 20, 21 under the action of springs 39. The arms 14, 15 are carried on spring-loaded friction pivots 12, 13 respectively. In operation, assuming that belt 3 is to be raised, handle 24 is moved to the left so that jockey pulley 17 forces the belt from its groove in drive-pulley 2 and the slackened belt is then moved upwards into the next groove in pulley 1 by the action of spring 39. For operation in the reverse direction pulley 16 disengages and pulley 19 re-engages the belt. In the lowermost position of the belt a cam 35, Fig. 2 (not shown), is operated to force the member 30 carrying jockey pulley 16 outwards against a spring 38, so that pulley 16 is moved nearer drive-pulley 1. An indexing detent 26 is provided.

[Also in Division H3] In an inverter including a controlled rectifier and an LC input filter-particularly an inverter as described in Specification 1,046,754-the inductor 28 of the filter is made larger than normal to prevent temporary disturbances blowing a protective fuse 29. Disturbances such as overload or shortcircuiting of the load circuit or misfiring of a non-conducting rectifier all result in the continuation of conduction in a rectifier which should have shut off, thereby producing an effective short circuit across the supply terminals through the inductor 28, the effective input inductance 7<SP>1</SP> of the inverter circuit, and a rectifier 1 or 1<SP>1</SP> (the inductance 7<SP>1</SP> being derived from transformers 7 and 3). This is diagrammatically indicated in Fig. 2 (not shown). The Specification shows mathematically that if the inductor 28 is more than 4À62 times as large as the input inductance 7<SP>1</SP> the oscillatory circuit of inductor 28 and capacitor 31 operates so that the voltage across the capacitor 31 goes to zero and the rectifier is shut off.

Title: Waveguide feed assembly for circular or linear polarization
IPC: H01P1/17
Filed: 1959-10-06
Abstract: 861,214. Waveguides. BENDIX CORPORATION. Oct. 6, 1959 [Oct. 16, 1958], No. 33873/59. Class 40 (8). A coupling between a rectangular waveguide and a horn comprises means whereby the polarization of the radiated energy may be changed at will from linear to circular and vice versa. The mode converter comprises three discs 14, 15, 16 having aligned central apertures which together form a circular waveguide. In each aperture is arranged a diametral rod 17. The discs have a thickness of one quarterwavelength and are assembled between a front plate 2 and a back plate 3, also one quarterwavelength thick. The back plate 3 comprises a waveguide section 4 designed to transform between the H 01  mode existing in a rectangular waveguide (not shown) and the H 11  mode in the discs 14, 15, 16. The front plate 2 comprises a section 5 of square waveguide corresponding to the square throat of horn 6. All the discs are rotatable and are mechanically coupled to each other by pin-and-slot mechanisms having a certain amount of lost motion. Two extreme angular positions of rest of the disc assembly are determined by stops 32, 33 in the back plate 3 which engage one or other of two shoulders 35 (one only shown) on the disc 16. In one angular position, the rods 17 are all in the same plane at right angles to the electric vector of the H 11  wave so that the linear polarization of the wave remains unchanged. In the other position, the rods lie respectively at angles of 45, 30 and 15 degrees to their original positions and effect a 45 degree rotation of the transmitted wave. A dielectric plate 8 in the throat of horn 6 is arranged to produce a 70-degree phase-shift between the equal orthogonal components of the obliquely polarized wave. The asymmetrical flare of the horn 6 produces a further 20 degrees of differential phase-shift, the total phase-shift amounting to 90 degrees whereby the polarization is transformed from linear to circular. The actuating mechanism comprises a toothed wheel engaging the toothed periphery of the disc 14. A handle 25 connected to the shaft of the toothed wheel is retained by springs in either of its extreme positions. Elliptically polarized radiation may be obtained by changing the angular setting of the discs 14, 15, 16 and adjusting the position of the dielectric plate 8. For this purpose, the plate is connected by rods 9 through slots in the side of the horn to a yoke 10 which carries an adjusting screw 11. A septum 13 equalizes the radiation pattern for the two components of the wave.
